Infectious Bronchitis-wrinkled eggs, safe to eat?

I have been getting one wrinkled egg almost every day out of my 9 hen RIR flock. After much reading it appears the likely cause is Infectious Bronchitis. Are these eggs safe to eat? Are the other's egss safe to eat? Is it contagious to people in any way? Also I occasionally see a brown spec in the egg white. Is this normal and is it indicative of anything.

A friend of mine had to cull her flock due to IB. The vet said the birds were safe to eat, so I guess the eggs would be as well.
Since IB is highly contagious, (so I have been told), the wrinkled eggs may be from another cause. I have read that sometimes an egg will bump into the next one and cause a wrinkle.

I don't know for sure that it is IB causing the wrinkled eggs however from my research, it is the most likely cause. They look more than bumped in to, they are significanty wrinkled all over. None of them appear sick, I guess I'll just keep watching.

are the whites watery too? Sounds like IB to me. Eggs are perfectly safe to eat, but you may wish to consider having a closed flock now if you don't already as your birds will now be carriers of the disease.
